Guest: Dr. Bob Hazen Mike is joined by his Carnegie Science colleague Dr. Bob Hazen. Together, they have written a new popular science book titled "Time's Second Arrow: Evolution, Order, and a New Law of Nature," which launches on February 10, 2026. This book describes how the marvelously complex constituents of our universe came to be. Evolution, they boldly propose, is a universal phenomenon—not only in biology, but in the entire atomic, chemical, mineral, and physical universe. Showing how a natural process of selection for increasing function has shaped the universe since its inception, they explore how a new law of nature could possibly help us identify life on other planets and—perhaps—even understand the purpose and meaning of life on Earth in a new way.

Guest: Dr. Caleb Scharf Becoming a spacefaring civilization is a major transition in the story of life on Earth. Senior scientist for astrobiology at NASA Ames Dr. Caleb Scharf beams aboard to discuss the themes in his latest book, "The Giant Leap: Why Space Is the Next Frontier in the Evolution of Life," and what it all means for achieving a Star Trek future.

Guest: Dr. Kristina Šekrst Philosopher, linguist, and AI researcher Kristina Šekrst beams aboard to discuss the TNG episode "Darmok," where Picard and crew encounter the Tamarians, a species who only speak in metaphor. Why do we use metaphors? How would you lie in Tamarian? And can the universal translator ever exist? Follow us on Bluesky!

Guest: Dr. Anirudh Prabhu Mike brings aboard Dr. Anirudh Prabhu to discuss an exciting new study of theirs that uses machine learning trained on organic chemical data to detect the "whispers" of life—including photosynthetic life—in ancient rocks. This exciting technique could one day be used to seek out new life on strange new worlds. Mike & Anirudh's paper, "Organic geochemical evidence for life in Archean rocks identified by pyrolysis–GC–MS and supervised machine learning": https://www.pnas.org/doi/10.1073/pnas.2514534122 Follow us on Bluesky!
